My scientific specialty is chronobiology (circadian rhythms and photoperiodism), with additional interests in comparative physiology, animal behavior and evolution. I am not an MD so I cannot diagnose and treat your sleep problems. As well as writing this blog, I am also the Online Discussion Expert for PLoS. This is a personal blog and opinions within it in no way reflect the policies of PLoS. You can contact me at: Coturnix@gmail.com

A short post from April 17, 2005 that is a good starting reference for more detailed posts covering recent research in clock genetics (click on spider-clock icon to see the original). As I have mentioned before, there was quite an angst in the field of chronobiology around 1960s about the lack of…

A new paper just came out today on PLoS-Biology: Glucocorticoids Play a Key Role in Circadian Cell Cycle Rhythms. The paper is long and complicated, with many control experiments, etc, so I will just give you a very brief summary of the main finding. One of the three major hypotheses for the…

I wrote this post back on January 23, 2005. It explains how clock biologists think and how they design their experiments: So, are you ready to do chronobiological research? If so, here are some of the tips - the thought process that goes into starting one's research in chronobiology. First, you…

Chad wrote a neat history of (or should we say 'evolution of') clocks, as in "timekeeping instruments". He points out the biological clocks are "...sort of messy application, from the standpoint of physics..." and he is right - for us biologists, messier the better. We wallow in mess, cherish…

This post is perhaps not my best post, but is, by far, my most popular ever. Sick and tired of politics after the 2004 election I decided to start a science-only blog - Circadiana. After a couple of days of fiddling with the templae, on January 8, 2005, I posted the very first post, this one, at…
